TYPES OF WINDOW
SECURITY BARS

5 types of window bars explained side by side — pros, cons, prices, and which one fits your situation.

Updated: May 2026 · SWB Compliance Team

Quick Answer

For most homeowners: telescopic + modular bars (Model A) are the best type — adjustable to any window, DIY in 15–30 min, from $85, 5-star security rating. Bedrooms need quick-release (Model A/EXIT). Renters with no-drill restrictions should use tension bars as a deterrent only. Fixed welded bars are overkill for residential use and cost 3–5× more.
